Housing Temperature Impacts the Systemic and Tissue-Specific Molecular Responses to Cancer in Mice.
Article in Journal of cachexia, sarcopenia and muscle, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCancer cachexia, affecting up to 80% of patients with cancer, is characterized by muscle and fat loss with functional decline. Preclinical research seeks to uncover the molecular mechanisms underlying cachexia to identify potential targets. Housing laboratory mice at ambient temperature induces cold stress, triggering thermogenic activity and metabolic adaptations. Yet, the impact of housing temperature on preclinical cachexia remains unknown.
methodsColon 26 carcinoma (C26)-bearing and PBS-inoculated (Ctrl) mice were housed at standard (ST; 20°C-22°C) or thermoneutral temperature (TN; 28°C-32°C). They were monitored for body weight, composition, food intake and systemic factors. Upon necropsy, tissues were weighed and used for evaluation of ex vivo force and respiration, or snap frozen for biochemical assays.
resultsC26 mice lost 7.5% body weight (p = 0.0001 vs. Ctrls), accounted by decreased fat mass (-35%, p < 0.0001 vs. Ctrls), showing mild cachexia irrespective of housing temperature. All C26 mice exhibited reduced force (-40%, p < 0.0001 vs. Ctrls) and increased atrogene expression (3-fold, p < 0.003 vs. Ctrls). Cancer altered white adipose tissue (WAT)'s functional gene signature (49%, p < 0.05 vs. Ctrls), whereas housing temperature reduced brown adipose tissue (BAT)'s (-78%, p < 0.05 vs. ST Ctrl). Thermogenic capacity measured by Ucp1 expression decreased upon cancer in both WAT and BAT (-93% and -63%, p < 0.0044 vs. Ctrls). Cancer-driven glucose intolerance was noted at ST (26%, p = 0.0192 vs. ST Ctrl), but restored at TN (-23%, p = 0.005 vs. ST C26). Circulating FGF21, GDF-15 and IL-6 increased in all C26 mice (4-fold, p < 0.009 vs. Ctrls), with a greater effect on IL-6 at TN (76%, p = 0.0018 vs. ST C26). Tumour and WAT Il6 mRNA levels remained unchanged, while cancer induced skeletal muscle (SkM) Il6 (2-fold, p = 0.0016 vs. Ctrls) at both temperatures. BAT Il6 was only induced in C26 mice at TN (116%, p = 0.0087 vs. ST C26). At the bioenergetics level, cancer increased SkM SERCA ATPase activity at ST (4-fold, p = 0.0108 vs. ST Ctrl) but not at TN. In BAT, O
conclusionsIn mild cachexia, BAT and SkM bioenergetics are susceptible to different housing temperatures, which influences cancer-induced alterations in glucose metabolism and systemic responses.
